Dari or Dari Persian or Eastern Persian is a name given to the Old Persian language at a very early date and widely attested in Arabic and Persian texts since the 10th century. Since 1964, Dari is the official name for the Persian language in Afghanistan. Dari Persian spoken in Afghanistan is formal version of the New Persian language descended from the courtly language of the Sassanian Empire and is thus more akin to the Middle Persian language than the dialects spoken in Iran or the Tajik dialect of Central Asia. In historical usage, Dari refers to the Middle Persian court language of the Sassanids.

A dopamine reuptake inhibitor (DRI) is a type of drug that acts as a reuptake inhibitor for the neurotransmitter dopamine by blocking the action of the dopamine transporter (DAT). Reuptake inhibition is achieved when extracellular dopamine not absorbed by the post-synaptic neuron is blocked from re-entering the pre-synaptic neuron. This, in turn, leads to increased extracellular concentrations of dopamine and therefore an increase in dopaminergic neurotransmission.
